ABC filed a legal motion with the FCC accusing the Trump administration of violating its First Amendment rights through regulatory scrutiny targeting the talk show 'The View,' alleging the FCC investigation creates a chilling effect on speech. The claim is confirmed by Reuters, NYT, Guardian, NBC, NY Mag, and local outlets. The language 'sued Trump in a major lawsuit' is slightly informal — it was technically an FCC filing rather than a traditional lawsuit — but the core allegation is verified and accurate.
